If by "absolute path" you mean the path to the application executable, than that's expected behaviour. Applications always specify 0x00400000 as their preferred load address. In general modules may be relocated because their preferred load address conflicts with the address of some other module. But because no user space DLLs are loaded before the application, their preference is always respected. so long, benny -- ISION Internet AG Benjamin Riefenstahl mailto:benjamin.riefenstahl@ision.net Harburger Schlossstr. 1 D-21079 Hamburg http://www.ision.net -- Want to unsubscribe from this list?
